ctaDescription.text = "In order to record video in the DV format on Mini DV tape, you will need a digital camcorder. There are several makes and models available, varying in price from to over USD$5000. Some DV camcorders are very small and compact, such as the one picture to the left.

This DV camcorder fits nicely in the palm of your hand, and can fit in a large coat pocket very easily. Cheaper DV camcorders usually have a single CCD, or Charged Coupled Device. The CCD is the electronically sensitive plate that receives the light coming in through the camera's lens. Since light is comprised of three color spectrums (Red, Green, and Blue), each pixel on the CCD is divided into three separate color receptors.

Low-end DV camcorders usually have very basic exposure controls for the video image, and little or no control over the audio sensitivity of the camera's microphone.";
